image correlation

[CJ Lin]

Hi,
     I have two images(the first two images, k1, k2), and I want to know the correlation with the other one. And the images are the coefficient fitting results with time-series analysis. And now, we hope to know these two images correlation pixel by pixel (mapping). But I have no idea how to do it in imageJ program, is there any methods to do the image correlation?

And I have try others code to do a correlation like the third image, but I have no idea is true or faith.
